Hello Everyone,

I want to share a project I have been working on for the last year. It is a quadcopter controller with full Linux support (maintained using buildroot)

This means:

  • full networking support (Wifi, Bluetooth)
  • use scripting or any programming language you want
  • SSH, Busybox, and hundreds of other tools
  • compile your own additional tools 
  • video4linux/camera (when using capable board - i.e. Odroid-W or RPi)
  • anything else Linux supports

The controller's features currently are:

  • Support for quadcopters in X configuration of any size
  • 2 fly modes - Auto-level & Acro
  • Altitude hold
  • learner mode (attach 2 controller simultaneously - one for the teacher and one for the learner)
  • fast (boot time of around 2-3sec)
  • WWW configurable (i.e. you can adjust anything using your phone in the field)
  • Camera support for taking pictures and videos
  • Live and Offline log charting (vibrations, quaternions, altitude, etc)
  • Out of box bluetooth (PAN) and WIFI connectivity for receiving flight logs, accessing the file system (NFS and SSH), browsing videos and pictures
  • Endlessly and easily extensible


The setup is relatively simple and includes 2 boards - AVR board (like Arduino Pro Mini) and SPI capable SBC (like Odroid W or RPi) wired together using SPI.

With the software provided the setup is of plug-and-play and you can control your quadcopter using PS3 controller or via network.

See the wiki for more information.

If you passionate about linux and quadcopters than this is something you should try! :)

Let me know if you have any questions.

Thanks,
Gregory

Depends on what exactly you want to do. Check the AvrMiniCopter architecture: https://github.com/rpicopter/AvrMiniCopter-wiki/wiki/Design

If you want to hack the code that controls the quadcopter then you only need Arduino IDE. However if you want to recompile the Raspberry Pi/Odroid image then you need buildroot.

Hello.
Yes I want to modify the code.
I want to know what Rapbian version you use to boot very quickry and small size.

Hi,

This is not Raspbian what we are using. It is a custom build linux distribution. 

I will do a writeup of how to compile it if I get some time but the basic steps are in here:

Thank you very much Gregory D for writeup of how to compile it.

Hi, How is it going, is it already flying?

Not yet. I can't to compile your code.

I've updated the installation scripts and readme.

Compile instructions you will find in the README:

https://github.com/rpicopter/buildroot

Thank you.

I want to know. How altitude hold work?

Hi, what exactly are you trying to find out - how to activate altitude hold or what are the implementation details?

There is a new version available. You will need to configure the hover throttle before using altitude hold.

I want to know  implementation details of altitude hold mode. I want appy to use for my firmware.
